Site diversity gain prediction models were created to estimate mathematically the acquired benefits from the implementation of site diversity at place of choice. This work contributes to the comparison of existing gain prediction model to the gain of measured attenuation at Cyberjaya and Rawang, Malaysia. The experiment has been conducted for 4 years from 2014 to 2017, in Ka band using a large 7.3-m diameter antenna and a high elevation angle of 68.8°, together with the rain analysis at both places for the same duration. The average monthly rainfall and attenuation for 4 years were presented. The results revealed that prediction model Hodge performs better than other models, while X. Yeo and Panagopoulos models appear to exhibit very similar graph shape to the measured gain data. More research on gain development in tropical region should be conducted, as the existing prediction model appears to be less consistent with the current data.

在热带气候下使用7.3 m天线直径在Ka波段中的站点多样性表现:预测模型的比较

创建了站点多样性增益预测模型,以数学方式估算从所选地点实施站点多样性所获得的收益。这项工作有助于将现有增益预测模型与马来西亚赛城和Rawang的测量衰减增益进行比较。该实验从2014年到2017年已经进行了4年,在Ka波段使用直径7.3 m的大型天线和68.8°的高仰角进行了实验,并在两个地方进行了相同时间的降雨分析。介绍了4年的平均月降雨量和衰减量。结果表明,预测模型Hodge的性能优于其他模型,而X. Yeo和Panagopoulos模型似乎表现出与测得的增益数据非常相似的图形形状。
